Let's divide 69039249 by 866
We want to figure out the number of times 69039249 can be divided by 866.

Going ahead to step 1:
866 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 866

Moving on to step 2:
866 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 866

Step 3:
When dividing 690 by 866, we get 0 with a remainder of 690.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 690 to get 690.
Include the next digit (3) from the dividend after 690, then repeat: 6903 / 866

On to step 4:
When dividing 6903 by 866, we get 7 with a remainder of 841.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 6062 from 6903 leaves us with 841.
Take the next digit (9) from the dividend and append it to 841, then repeat: 8419 / 866

On to step 5:
866 can be fit into 8419 9 times, resulting in a remainder of 625.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 7794 away from 8419, we end up with 625.
Include the next digit (2) from the dividend after 625, then repeat: 6252 / 866

Moving on to step 6:
When dividing 6252 by 866, we get 7 with a remainder of 190.
Use 7 as the next digit of our solution. 
Result so far: 797.0
The remainder is 190 after subtracting 6062 from 6252.
Take the next digit (4) from the dividend and append it to 190, then repeat: 1904 / 866

Moving on to step 7:
The number 866 fits into 1904 2 times, leaving a remainder of 172.
Use 2 as the next digit of our solution. 
Result so far: 7972.0
Subtracting 1732 from 1904 leaves us with 172.
Take the next digit (9) from the dividend and append it to 172, then repeat: 1729 / 866

Step 8:
866 can be fit into 1729 1 times, resulting in a remainder of 863.
The next digit of our result is 1. 
Result so far: 79721.0
If we take 866 away from 1729, we end up with 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Going ahead to step 9:
8630 divided by 866 is 9 with a remainder of 836.
Put 9 as the next digit of the answer. 
Result so far: 79721.9
If we take 7794 away from 8630, we end up with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Step 10:
866 goes into 8360 9 times with a remainder of 566.
Record the quotient 9 as the next digit in the result. 
Result so far: 79721.99
Deduct 7794 from 8360 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Our division results in 79721.99 with a remaining 0.566.
